中国科学院上海光学精密机械研究所光子技术实验室在飞秒激光诱导微纳功能结构研究方面取得新的重要进展,研究发展了一种新的计算全息方法。该方法利用飞秒激光直写在金属薄膜上形成计算全息图,不需要掩模且不必对基体材料做清洗、刻蚀等特殊的前期及后期处理,通过模拟算法,设 Photonic Technology Laboratory, Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences has made new and important progress in the research on the functional structure of micro-nano induced by femtosecond laser. A new computational holographic method has been developed. The method utilizes femtosecond laser direct writing to form a computing hologram on a metal film, does not need a mask and does not need to do special pre-processing and post-processing of the substrate material such as cleaning and etching. Through the simulation algorithm,
